Hi Guys,
With Gerberas you need to remember that they have HIGH energy requirements. This means that they need HIGH energy fertiliser (high potassium requirements). If you want your plants to remain looking as vibrant as they were when you bought them from plant nursery - you will need to apply HIGH energy fertiliser once or twice a week.
Just apply fertiliser with waterings. Don't overwater plant as this can lead to crown rot and/ or wilted flowers.
Good luck with your lovely gerbera plants,
mowie
